Subject: [PATCH -fixes v2 2/3] riscv: Do not set initial_boot_params to the linear address of the dtb
Date: Wed, 29 Mar 2023 10:19:31 +0200	[thread overview]
Message-ID: <20230329081932.79831-3-alexghiti@rivosinc.com> (raw)
In-Reply-To: <20230329081932.79831-1-alexghiti@rivosinc.com>

early_init_dt_verify() is already called in parse_dtb() and since the dtb
address does not change anymore (it is now in the fixmap region), no need
to reset initial_boot_params by calling early_init_dt_verify() again.
